K5 Media

Update: These themes are no longer listed on the K5media site, but Black Splat has now been released as a free theme.

K5 Media first came to my attention last year when I came across SweetCorners, a free/sponsored theme created by them (which is no longer available).

They currently have three attractive themes for sale, each of which are widget and Adsense ready.
